| The upper pull rods 21MG40.11.13.99 of the coal mill play a vital role in the medium-speed coal mill. The upper pull rod is connected to the upper pressure frame through a spherical self-aligning bearing. This structure enables the pull rod to effectively transmit the hydraulic loading force, thereby controlling the grinding output of the coal mill. During the operation of the coal mill, the pull rod not only bears a large mechanical load, but also faces the challenges of wear and corrosion. Therefore, the material selection and structural design of the pull rod are crucial to its performance. It is usually made of high-strength steel to ensure its stability and durability under high load conditions. In addition, the upper pull rods 21MG40.11.13.99 also has a monitoring function. A measuring scale device that can display the coal seam depth and wear condition of the wear-resistant parts of the coal mill is installed next to the pull rod. This enables the operator to understand the operating status of the coal mill from the outside during the operation of the coal mill, and to perform maintenance and adjustments in time. Through these functions, the upper pull rods provide a strong guarantee for the efficient and stable operation of the coal mill. |
